Abstract

original image

Various microstructures including straight filaments, layer-by-layer scaffolds and freeform helical spirals are fabricated by a solvent-cast three-dimensional printing technique, as reported by D. Therriault and co-workers on page 4118. The fabrication capabilities of this powerful and flexible process are demonstrated by the printing of three microsystems featuring mechanical, microfluidic and electrical functionalities, such as a high-toughness microstructured fiber, a 3D microchannel and a Ka band antenna. These capabilities can be extended through the utilization of other thermoplastic-based inks and the printing of features at the sub-micrometer- and potentially nanoscale.
